The frame is completed by justed position, whereby the sash are likewise the closure plate 29 having straight end portions locked in the adjusted position so long as the and an arcuate intermediate portion 2: which is operating linkage and Window operator are operaslotted substantially throughout its length as tively connected. at 22.

Other and further objects, features and advan- A horizontal pivot pin 23 extends between the tages will be apparent from the description which side members It and I? substantially intermediate follows, read in connection with the accompanytheir ends and, for convenience in assembly, may ing drawings in which have threaded connection therewith as illustrated Figure 1 is a front elevation of the lower portion in Figure 4. A lever 26, journalled on the pivot cally disposed operatingelinkage which cohnebfis the several sash.

pin 23 is pivotally connected at its distal end to the lower end of the lowermost link I5 and is provided with a tail portion 25 extending beyond the pivot pin 23 in the direction away from the link l5.

Also journalled on the pivot pin 23 is a particylindrical drum-like enclosure 26 comprising side walls 21, 28 and an arcuate wall 29 which makes Sliding engagement with the closure plate 28 of the supporting frame. Fixed in the wall 29 of the enclosure .26 and extending outwardly through the slot 22 of the closure plate 20 is a radial stud 30 on which is threaded a handle 3|. A spring washer 32 is preferably mounted on the stud 30 between the handle 3| and the closure plate 20.

A clutch member 33 comprises a rod 34 slidably mounted in a suitable aperture in the wall 29 of the enclosure 26, and a U-shaped yoke 35 secured on the inner end of said rod. The yoke is connected by means of a small spring 36 with a fixed strut 31 extending between the walls 21 and 28 of the enclosure 26 and serves as a toggle spring to maintain the clutch member 33 in either of its extreme positions. A second strut 24 fixed to and extending between the walls 21 and 28, serves as a limit stop for the angular movement of lever 24 in the downward direction, while the yoke 35, by engagement with the tail portion 25 of the lever, serves to limit movement of the latter in the upward direction. For ease in manipulating the clutch the outer end of the rod 34 is provided with a handle in the form of a ring 38.

As will be seen from Figure 3, when the clutch 33 is in its outer or left-hand position, as shown in solid lines, the yoke 35 engages the tail portion 25 of the lever 24, and also the arcuate Wall 29 of the enclosure 26, and thus serves as a wedge or block acting between the two, firmly holding the lever 24 against the stud 24, in the position shown in solid line in Figure 3. Under such circumstances, the lever 24 is rigidly connected to the handle 3|, and the windows may be opened and closed by manipulation of the latter. When, however, it is desired to disengage the handle from the operating linkage so that the sash may open to their counterbalanced position and may thereafter be closed by gravity in case of a rainfall, the clutch 33 is moved to itsinner or righthand position, as shown in dotted lines in Figure 3. In this position, the yoke 35 occupies such a position that the lever 24 may swing about the pivot pin 23 into the position shown in broken lines, permitting the sash to open regardless of the position of handle 3|. When the sash are closed by gravity, as in the case of a fall of rain, the lever 24 will, of course, return to the position shown in solid lines.

With the clutch in its left-hand or engaged 4 position. the sash may be locked in any desired attitude by tightening the handle 3| against the spring washer 32 and closure plate 20.

As will readily be understood, opening Or closing the sash by means of a simple movement of the handle 3| through a small angle represents a considerable advantage as compared to performing the same o eration by the conventional means while at the same time the lever-type operation enables the use of the simple and inexpensive clutch device of the present invention for releasing the sash for gravity or rain operation when desired.

Having thus described the invention, what is claimed as new and desired to be obtained by Letters Patent is:

1. In a window assembly of the type including a plurality of horizontally pivoted sash in vertical series and connected by a common linkage for simultaneous opening and closing movements, 8. window operating device comprisin a supporting frame, a horizontal pivot supported thereon, a lever mounted for vertical angular movement on said pivot, said lever being adapted for connection to said linkage and having a tail portion extending beyond said pivot in the direction away from said linkage, a manually operable member mounted for vertical angular movement about said pivot, and a clutch member mounted for angular movement with said manually operable member and slidable relative thereto into and out of engagement with said tail portion of said lever, said manually operable member comprising a hollow enclosure, and said clutch member comprising a portion which in the engaged position abuts said tail portion on one side and a wall of said enclosure on the other side.

2. A window operator according to claim 1. including resilient means connected as a toggle spring between said clutch member and a wall 01' said enclosure to yieldingly retain said clutch member in one or the other extreme position.
